1 o uit @from at may concern:

Be it known that I, JOSEPH H. CHASE, a citizen of the United States, aresident of the city of New York, in the countyland Stute of New York,have invented an Improvement in Note-Sheet Spools, of which thefollowing is o specification. f This invention relates to music rollspools such as are commonly used in player-pauos or the like to carrythe music roll or `note sheet. The principal object of the 4inventloniis to improve the construction of such spools so that they may be moreeasily` handled and may be more economicallypacked for shipment orstorage. z For lthe purpose of illustration. and description, oneembodiment of the invention the accompanying drawings, and therein l fF'gure 1 is a perspective view of gz no to sheetl spool embed ing theinventiqn,to.' hcrefor,- shown Qxidotted lines; f- Fig. 2 is a centrallongitudinal Section through the note sheet spooljffnd box* 'and Fig. 3is a cross section'thrbughtheoontaining box adjacent the endo the'spool.

In the handling of music rolls of the usual construction it is oftennecessaryjto exercise great care when ll yin Athem'Adovcfn upon anysmooth surface inori-'r that they may not roll fromthe top of the bible,cabinet or! the likeupomwliich they may-hoppen to be placed? This is4:due to the circular flanges Yofthe note sheet spool. Music rolls areusually packed in small boxes approximating in interior cross sectionthe diameter of the end flanges o1 the spool. It has been observed thatthese boxes are very apt to breuk through where the periphery of vtheend Hanne contacts with the bottom of the box. rl he note sheet spool isgenerally entirely supported within the box by contact of the spoolflanges with the bottoni of the box nt only two oints. When the boxconr:lining its spool 1s roughly handled the note sheet spool, beingmuch heavier than the box. tends to deliver concentrated blow upon thetwo points; nliere the unges contact with the bottom of the box. `'lo helimited area. of Contact, therefore, may be nttribu ted the ,/t'rei'einthe spool "fing end il Vit 1s octagonal center .is at the axisbelreadily understood that a note sheet spool 7o provided with suchflanges will no l box.

frequent The present invention seeks to over` suggested. The

boxes. collie the difficulties here mcuns herein shown for desiredresult will new be described.

Fig. 1 .of the drawings shows n note sheet spool embodying the presentinvention and comprises a spindle 1 havunges 2 and 3 :my suitablemanner. The usual recesses are provided in the hubs of the flanges forengagement by the usual shafts journaled in" the spool box of a piano.The periphery of the spool fl irregular, and specifically 'in thedrawings in shape, with strnight or` tions 4 forming chords of a circleW ose of the spool. It will t readily roll along the surface of o tableor the like, btitvvill remain substantially in the position in which itis first placed.

Referring to the ventioli: The shape of vthe flange herein shownennb'les boxes of smaller cross section to be used with this type ofmusic roll, than could .be used if the end flan: es were circulur usgenerally the ruse. 'i 1l an economy of box material., and furthermore.us .shown in Fig. 3, thespool flan es `will have u substantialureazoffeoritact wlth,

I claim us my invention:

l. A note sheet spool having pol gonal end [langes: said spool beingadapte to fit ow delivered y the a substantial area, and theftillgreatly minimize the fied and ein?r i rhin the scope of the subjoinedwithin a container of square cross-section,

thereby providinsubstantial :i1-cas of con,

tact between'sai end anges and the in- Lerior of said container.

2. A n ote sheet spool having octagonal md Hongos, said spool beingadapted to fit Nithin acontainer of square cross-section,

thereby providing substantial :irons of con tact between said und nngesand the interior of the container.

In testimony whereof, I have signed my llame to this specification this9th day of November, 1916.
